Specification 0! Letters Patent.-

Patented Sept. 22, 1908.

Application filed January 24, 1908. Serial No. 412,380.

To all whom. it may concern:

Be it known that I, Rumor-:1. E. NonttsT, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Im )rovements in Guardand (leaning Attaclunents for Stock-Watering Troughs, of which thefollowing is a specifica tron.

This invention relates to guard and cleaningz attachments 'for stockwatering troughs, and my object is to produce an efficient attachment ofthe character named which can be instantly )laced in or removed from atrough but which cannot be dislodged from or disarrangcd in the troughby hogs or other stock.

A further object is to produce an attachment which eflicient-ly guardsthe float from injury by the stock and by which trash and muddy watercan be withdrawn from the trough without moving the same.

A still further object is to produce a device, which in more or lessmodification of: form and size, ca be applied to any of the aproredtypes of automatically filling watermg troughs now in use.

With these objects in view the invention consists in certain novel andpeculiar features of construction and organization as hereinafterdescribed and claimed; amt in order that. it may be fully understoodreference is to be had to the accompanying drawing. in which,

Figure l, is a central vertical transverse section of a watering troughequipped with an attachment embodying my invention and shown inoperative relation to a sup )ly tank. Fig. 2. is a central verticallongitudinal section of a trough and attachment. Fig. 3 is a detailperspective view of the attachment.

In the said drawings 1 indicates a watering trough of the usual or anypreferred type, the trough shown being of elongated form withsemi-circular or rounded ends.

2 is an opening in the side of the trough and projecting into the latterthrough said opening is the nipple 3 of a. plate 4 riveted or otherwisesecured to the trough and provided with a threaded pass 5. engaging saidthreade passage and provided with a. pair of inwardly projecting lugs 7.

S is a valve adapted to seat against the outer end of the nut'6 andcarried by a. bolt 9 pivoted at its inner end to a ductile lever 10 6indicates a nut fulcrumed at 11 to and between lugs 7 and equipped atits free end with a float 12.

13 isa pipe connecting plate 4 with a supply-tank 14 of any suitablecharacter, said tank being adapted to stand charged with water which isada ted to flow into the trough and keep the latter charged to apredetermined depth, this depth being regulated by bending the ductilelever 10 so as to vary the position of the float vertically.

For the purpose of protecting the float from injury by the stock and toeffect the removal of dirt, trash and muddv water from the troughwhenever desired, provide an attachment preferably of sheet metal andconsisting of an arched portion 15 of greater depth by preference thanthe trough and adapted to tit therein over the float and valveconnections. arch a pair of arms 16 project. These arms fitting with acomparative degree of snugness against the sides and ends of the troughthou h not so tightly as to revent the water which enters the trough ifrom occupying the portions of the trough at opposite sides of the arch,that is the portions forming the drinking chambers or compartments.

To stifl'en the arms and also to insure the retention thereon of dirt ortrash, they are provided with shallow or low marginal walls 17, and tostiffen the arch similar walls or flanges 18 are provided, the upperportions of flan es 18 being bentor hammered down upon the roundedportion of the arch as at 19 in order to permitthe caps 20 to be fittedsnugly on the arch, said caps having inwardly projecting flanges 21fittingover the flattened flanges l9 and being secured to the arch byrivet-s 22. These caps 20 close the ends of the arch to'a lane below theupper edge of the trough and thus guard against a. hog getting his noseunder the arch and possibly dislodging the attachment. or disarrangingthe float.

The attachment maintains its position in the trough by gravity andcannot be removed except by grasping its arch and pulling directlyupward, the result of this action, if performed quickly, being to liftpractically all of the water out of the drinking chambers together withany mud or trash which has settled upon the arms. The attachment canthen be slipped back into position, ,it being noticed that no bolts 'orfastening devices of From the lower ends of the eneath the arch any kindare employed to secure the attach ment in position.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent, is

l. Thecombination with a watering trough of a supply tank connected tosaid watering trough throu h one of the walls thereof, a valve controling such connection, a float connected to the valve and located in thetrough and adapted when the latter is charged with the required volumeof water to cause said'valve to close and when the water level in thetrough falls, to descend and open said valve, and an attachment fittingin said trough and comprising an arched central portion overlying andprotecting or guarding the float, and arms projecting outwardly from thelower ends of said arch and substantially covering the bottom of thetrough at opposite sides of the arch.

2. A watering trough attachment, comprising an arch aving outwardlyprojecting arms at its lower ends equipped with marginal walls.

3. The combination with a watering trough of a sup" ly' tank connectedto said watering trough t roufih one of the walls thereof, a

trough at o posite sides of the arch, and

flanges or we ls rojectin upwardly from the margins of sai outwar yrojecting arms. In testimony whereof I a my signature,

in the presence of two witnesses.
